Abstract

Bulus, her biri bir çok istifli seviyeden olusan üç bölgeye ayrilmis çok ocakli bir firin içinde gerçeklestirilen , agir metal içeren tortularin isi ile isleme tabi tutulmasi yöntemi ile ilgilidir.Adi geçen yöntem asagidaki asamalardan olusur: agir metal tortularinin çok ocakli firinin birinci bölümünün en üst seviyesine sürekli olarak beslemesi,tortular ikinci bölgeye dereceli olarak geçirilir ve geçirilme sirasinda kurutulur; indirgeyici maddelerin ve sülfür giderici maddelerin ikinci bölgenin en üst seviyesine sürekli olarak beslenmesi,bu sekilde indirgeyici maddeler ve sülfür giderici maddeler, kurutulmus tortular ile karistirilir ve karisim yaklasik 800 C' ye kadar isitilir, isitma sirasinda yakarak kireçlendirilir ve üçüncü bölgeye dereceli olarak geçirilir; karisimin üçüncü bölgede yaklasik 1000 C' ye kadar isitilmasi, bu sekilde metaller indirgenir ve adi geçen üçüncü bölgede üretilen atik gazlar ayrica çekilir ve isleme tabi tutulur;ve karisimin çok ocakli firindan DEVAMIThe invention relates to the process of treating residues containing heavy metal, which are carried out in a multi-hob furnace, each of which is made up of several stacked levels. The above mentioned method consists of the following stages: continuous feeding, the deposits are gradually passed to the second zone and dried during passage; Continuous feeding of reducing agents and desulfurizing agents to the top level of the second zone, the reducing agents and desulfurizing agents are mixed with dried sediments and the mixture is heated to approx. 800 C, burned during heating and scaled to the third zone; heating the mixture to about 1000 C in the third zone, the metals are reduced in this way and the waste gases produced in the third zone are extracted and treated separately; and
